ELECTRIC SIGNAL.

No. 959,766. r

'3 To wll'wham it may concern:

.Be it known that we, EMILE InoNArs, a

citizen of Canada, and WILLiAM T. SUTTON,

a citizen of Canada, and. both residents of Montreal, in the Provinceof Quebec and Do- 'mi11ion of Canada, have invented a new and Improved Electric Signal, of which the folglowingis a full, clear, and exact description.

Our invention relates to electric si nals,

and nioreparticularly to asystem for ringing 1 one or more electric bells from a distance.

'. .Ou'rinvention further relates to a system jfiWbichm, rela is employed for controllin a bell and. in w ch a single battery is used forl energizing the relay and for operating the be 1.

Among the several advantages presented by our invntion'j are the following: First,

the batteryis comparatively near the bell and its current is virtually shifted for the purpose offring'ingjthebellj second, the reay-magnetan [the bell-magnet are of proper resistance to so 'apportion the current as to economize the battery energy; third, the

.' I efiici'ency of the system as a whole.

" latter being 1 Reference is to be had to the accompany ing drawing, forming a part of this specification, in wh1ch the figure'shows a front elevation of the bell made in accordance with our invention, and also shows diagrammatically the Wiring connected with the bell for operatingthe same from a distance.

Mounted upon a wooden base 1 is a bell-- magnet 2," provided with an armature 3, the

"ournaled at 4 and free to swing.

A buffer 5, raving the form of an L-shaped piece of metal, is encircled by a sleeve 6 of felt or rubber and is provided with a slot 7,

upon' this frame at 14 is an armature 13.

through which asses a screw 8. The buffer is thus rendere adjustable toward and from the ma net 2 and is used for limiting the throw o the armature 3. Mounted'upon the armature '3'is a spring 9 of metal, provided with' a platinum tip 10. A relay-magnet 11 is mounted upon a frame'12, and journaled leaf-spring 1551313 to retract the armature 13 and engages a. stationary pin 16, An other stationary pin 17 serves as a limiting stop for the upstroke of the armature 13.

I pecification of Letters Patent.

I Application filed May 5, 1906. Serial No. 315.413.

' Patented April 16, 19o7 The spring 15 thus tensions the armature 13 and normally sustains it in the position indieated. I

A leaf-spring 18 isconnected with the armature and rests upon a pin 19. The tendency of the spring 18 is to maintain the armature 3 normally in engagement with the buffer 5, or, in other words, is to retract the armature 3 after the same has been drawn to the right of the bell-magnet 2, Rigidly connected with the armature 1 3 and de ending.

downwardly therefrom is an arm 20, t e lower end of which is provided with a contact-boss 21 of platinum. This contact-boss projects into an aperture, 23 in a fiber plate 22, secured upon the framelZ. Whenever the armature L3 is attracted by the magnet 11, the arm 20 swings, to, the left, according to the view shown, so that the boss'21 projects fora certain distance to the left of-the plate 22. In

this position the boss 21 is engaged by the contact-point 10, provided the armature 3 is in its normal pos1t1on,.but not otherwise I that is to say, if, the armature is held down continuously the contact-point 10 engages the contact-boss 21 anddisen ages the same,

according to the osition an movementof the armature 3. be back late 24 pf the relay-magnet 11 is secured irectly u on the frame 12, and thus serves to support t e'magnet thereupon.

Binding-posts 25 26 27 are mounted upon the base 1. A battery is shown at, 28 and is connected by a Wire 29 .with the binding-post 25 This bindingpost is connected by a Wire 31 Withit he magnet'lland by a wlre 30 with the frame 12. A wire 32 extends from the bell-magnet 2 to the binding-post 27, the latter being connected by a wire 33 with the battery 28. The binding-post 26 is connected by a wire 34 with the relay-magnet 11. From the binding-post 26 a Wire 35 leads to'the ush- -button 36, which is normally open. ,rom

this ush-button a wire 37 leads back to the binding-post 27. W'ires 38 39 are connected with the wires 35 37 and may be'used for adding either additional bells or additional push-buttons to the system. The bell-gong is shown at 40 and is struck by the clapper.

-41, which is mounted upon the'upper'portion of the armature 3.

The operation of our device is as 'follows': We will suppose that the push-button 36 is located at some distance from the bell. The battery 28, however, is comparatively near the The parts being in normal posi- 1o being'in'normal position by tion, as indicated in the figure, the o erator closes the push-button 36. The following circuit is thereby completed, as follows: battery 28, wire 33, binding-post 27, wire 37,

5 push button 36,v wire 35, binding-post 26,

wire/34, relay-magnet 11, wire 31, bindingpost wire'29,'back to battery 28. This enegizes the relay-magnet 11' andcauses it to raw the. armature 131 The armature3,-

virtue of the tensionlof the spring 18, the boss 21 is pressed into en agement with the contact-point 10, the. following circuit being thereby completd: battery 28, wire 33, binding-post 27, I 5 wire 32,bell-magnet'2, journal 4, spring 9, contact-point 10, contact-boss 21, arm .20, frame 12, wireBO, binding-post 25, wire 29, back to battery 28. It Willbe noted-that this circuit is to some'extent in parallel-with the circuit first desoribed thatnis to say, the

battery 28 energizes'a circuit through the pushwbutton 36 and the relay-magnet 11, and atmomen'ts when'the boss 21 and the con- .tact-point 10am in enga ement there is a zgfshunt-circuitthroughthe 'ell magnet2. It 5 will also be noted that whenthepush-but-ton 36-is closed the entire energy of the current o crates upon the relay-magnet 11 and that a ter this magnet draws its armature comoj. paratively near to its poles the current is thus shunted ofl' to operate the=be1l. This arrangement is; quite important,- for the v reason that ifthe:armature 13 approaches comparatively near the poles of the magnet 5'1-1- comparatively little energy is now required to hold this 'armature,.and all of-the excess of energy canhe employed for ringing .the bell. By making the magnet 11 of comxparatively hlgh resistance it-need not absorb 40 any considerable ortion of the energy, so

that nearly all of th thrown upon the bell-magnet? The armae battery-current may be ture'13 being held firmly down, the contactpo1nt-10 and the boss 21 serve as an interru' ter and cause the current to flow inter Ililttently through the magnet 2, so that thearmature 13 is caused to vibrate substantially in the manner well known in this art. The bell-gong 40 is thus struck intermittently by the clapper 41. f 1

claim as new and desire to secure by Letters I Patent-- 1. A device of the classdescribed, eom-' prising a relay-magnet and an armature therefor, a bell, a magnet for the bell, and an armature for the magnet provided with a circuit between the terminals of thabattery' and the relay-magnet, a shunt-circuit in con nection with said first-named circuit and im hammer for the bell, abattery, an-electric eluding the bell-magnet, and means whereby the closing of themain circuit will closethe shunt circuit and whereby the openingof the main circuit will positively openthe shunt circuit,
